CVE-2025-27937
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedQuick Agent V3 and Quick Agent V2 contain an issue with improper limitation of a pathname to a restricted directory ('Path Traversal'). If exploited, an arbitrary file in the affected product may be obtained by a remote attacker who can log in to the product.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceQuick Agent V2 and V3 contain a path traversal vulnerability that allows authenticated remote attackers to read arbitrary files from the server filesystem by manipulating path inputs in the application.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Quick Agent installation and versionCheck the installed Quick Agent version via the application's main window 'About' section, or look for version info in the installation directory (typically in a version manifest or .dll properties).Affected if The installed version is Quick Agent V2 or V3 (no specific version ranges provided; compare to any known affected releases).
-
Verify authentication is enabledCheck the application's security settings or authentication configuration panel to confirm user authentication is required for access. In Quick Agent, this is typically found in Security or Access Control settings.Affected if The vulnerability requires an authenticated session - if anonymous or guest access is enabled without credentials, the path traversal may still be exploitable but the CVEs specifically note authenticated attackers.
-
Confirm file path input feature accessibilityLocate any feature in Quick Agent that accepts file or directory paths as input - this includes file import, export, backup/restore, or custom script/command execution features that reference filesystem paths.Affected if The path traversal vulnerability is exploitable only through path input fields in the application - if such features are not accessible to the user role, exploitation is not possible.
-
Inspect application logs for path traversal attemptsReview Quick Agent server or application logs for unusual path references like '../' sequences, absolute paths outside expected directories, or repeated file access attempts to sensitive system paths (e.g., /etc/passwd, Windows\System32\config).Affected if Log evidence shows path traversal patterns or access to files outside the application's intended directory structure.
A user is affected if Quick Agent V2 or V3 is installed with authentication enabled and a path input feature is accessible to authenticated users, as the vulnerability allows authenticated attackers to read arbitrary files via manipulated path inputs.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation to restrict file path access, apply principle of least privilege to file system permissions, and apply vendor patches when released.
